the series in general has been totally brilliant though. Especially the whale one. Whales still have vestigial hind legs because they evolved from something similar to a hippo! Only slight annoyance is dawkins being seemingly unable to say a single sentence without ending it with a smug 'YOU WOULDN'T EXPECT THIS IF IT WERE INTELLIGENT DESIGN'. Explaining how it is that anatomy has come to evolve to be less than optimal is fascinating stuff, but i'd rather he let the intelligent design proponents form their own conclusions rather than being smugly shoving it down their throats.
